Slide 1

The visible light we see from our Sun comes from which part?

1) core

2) corona

3) photosphere

4) chromosphere

5) convection zone

Slide 2

The visible light we see from our Sun comes from which part?

1) core

2) corona

3) photosphere

4) chromosphere

5) convection zone

The photosphere is a relatively narrow layer below the chromosphere and corona, with an average temperature of about 6000 K.

Slide 3

Click to add notesThe density of the Sun is most similar to that of

1) a comet.

2) Jupiter.

3) the Earth.

4) interstellar gas.

5) an asteroid.

Slide 4

The density of the Sun is most similar to that of

1) a comet.

2) Jupiter.

3) the Earth.

4) interstellar gas.

5) an asteroid.

The Sun is a ball of charged gas, without a solid surface.

Jupiter has a similar composition, but not enough mass to be a star.

Slide 5

The Sun is stable as a star because

1) gravity balances forces from pressure.

2) the rate of fusion equals the rate of fission.

3) radiation and convection balance.

4) mass is converted into energy.

5) fusion doesn’t depend on temperature.

Slide 6

The Sun is stable as a star because

1) gravity balances forces from pressure.

2) the rate of fusion equals the rate of fission.

3) radiation and convection balance.

4) mass is converted into energy.

5) fusion doesn’t depend on temperature.

The principle of Hydrostatic Equilibrium explains how stars maintain their stability.

Slide 7

The proton–proton cycle involves what kind of fusion process?

1) carbon (C) into oxygen (O)

2) helium (He) into carbon (C)

3) hydrogen (H) into helium (He)

4) neon (Ne) into silicon (Si)

5) oxygen (O) into iron (Fe)
